Application filedl May i3, 1918. Serial No. 234,122.

Be it known that l, MELUN Oviis'rnun, a citizen of the United States,`residing at Stillwater, in the county of Vashington and State oilvlinnesota, have invented a new and usc'ul lniproveinent. in Carriers,oit'. which the Afollowing is a specification.

T his invention relates to innroveinentsin power carriers, the primaryobject being to provide a carrier having a series oit rollers which arepositively driven in an eilirient manner to convey shells and otherarticles iii-oni place to place. further object is to provide a carrieroi' the character ystated in which a chain drive employed,

a single chain being adapted to travel over a series of sprockets whichare connected with ythe rollers to be driven; j

A further object is to provide, in conibination with such structure ahousing' which is adapted to hold the chain in niesh with the teeth cithe sprockets and protect the .chain'and sprockets so as to redu e thehazard o-anything catching in n ioving parts. li. still further objectis to provide in conibination with the structure stated means tortransferring articles from one length of can rier onto a transverselength of carrier, the articles being ina-de to turn sharp corners intransit. Vith these and other objects in view `inv invention comprisesthe ilieaturcs of construction and combinar-lim or parts here ina'iiterAparticularly described and i-lainied.

ln the accompanying drawing forming part ot' this specification, Figure1 1s a plan oit carrier mechanism ./gonstructed 1n accordance with myinvention; Fig. 2 is a side elevation of a detail oi one or the carriersections; Fig. 3 is a section taken on the line 3 3 of Fig. 2; Fig. el::is an end view of one of the bearings in which each end of each rollershaft is journaled, and Fig. is a section taken on the line of Fig. l ofone side or' the link belt employed for assisting in causing the shellsor other articles iny turning a square corner between one length ottcarrier and a transverselyv arranged length of carrier.

In the drawings let i and B represent two lengths of carrier constructedin accordance with niy invention, said lengths being arranged at rightangles to each other and the length B a little higher in elevation thanthe length A. interposed between the end of thelength B and the side ofthe length A is carrier.

a slide 10 down which the shells or other articles being conveyed areadapted to slide from the carrier B on to the carrier A. That portion ofthe carrier adjacent to the lower end of `the slide 10 is provided witha lini belt conveyer 1l on to which the lower ends of the shells orother articles pass and are carried forwardly in the direction or thearrows indicated in F ig. 1, thus deliecting the shells longitudinallyatright anglesr from the position in which they are advancing on carrierB into the position which they a-re made to assunie on the carrier A.

corners in transit, or can be'` deflected in their course at any angledesired.

With the exception o the feature stated, the' carrier A and B aresubstantially alike in construction each consisting of a. pair oli'longitudinal side rails 12 and 13 inade out of angle members, the lowersides of which extend inwardly and are secured Vto transverse spacingnieinbers such as 14k by bolts 15 (see Fig. 2) or other suitable ineans.At spaced intervals throughout the length of the side bars and arrangedoppositely to each other are pairs of circular openings 1G in theopstanding sides oi the anglo menibers 12 and 13. These openingsreceiveand hold the circular ends 17 (see Fig. t), bear ings 18, whichare placed on the angle nienibers and are prevented troni turning bytheir flat stability bases 19 which rest on the lower sides of the anglemembers. These y bearings form journals for the ends of the shafts 20which carry the bodies of the rollers 21. rThe surface ot the body ofeach roller 21 is of any suitable configuration to carry the articleswhich are to be conveyed .iy the carrier. he forni illustrated is onedesign in which the body portion is of less diameter' than the ends :22,said ends acting' as side guards to guide the articles in transit andprevent theni from rolling oft ofthe l Part of the bolts 15 which securethe spacing rods 14 to the side ineinber 12 also serve to secureupstanding brackets 23 (see F ig. 3) rigidly in place. Secured to. thesides of these upstanding. brackets by rivets 24 or other suitableineans is a longitudinal angle member ..5 having one of its sidesprojecting inwardly to assist in forining a housing which incloses theupper portions of sprocket wheels 26, there being one sprocket wheelmounted on the end of each rlhus the articles are inade to turn squarel'lO shaft 20 nearest the side member 12. The housing mentioned iscompleted by another longitudinal angle member 27, which is secured byrivets 28er other suitable means to the inwardly projecting side of theangle v ,member 25 with its opposite side depending ldownwardly adjacentto tie inner sides of ithe sprockets 26. This housing forms a hand guardrlhe sprockets 26 are secured to the shafts 20 by pins 29 or othersuitable means. The sprocket Wheels are driven by the upper side of achainrbelt 30, the links of which mesh with the teeth of said sprockets,the lower side of said belt hanging loosely and said belt receivinginitial power from any suitable source, that illustrated being a pul- 31mounted on one of the shafts 20 of one of the carrier rollers. The upperside of the housing formed by the pair of angle members 25 and 27 liessuiiiciently close to' the periphery of the teeth of the sprocket wheels26 to prevent the upper side ofthe belt 30 from disengaging said teeth.'The housing also acts as a guard to holdv the Vdrive belt in mesh withthe teeth of the sprocket and also to prevent clothing or anything fromunintentionally catching between the teeth and the chain, thus reducingand preventing danger. The journal blocks 18 are formed with receptacles32 in which lubricating medium may be placed from the shafts which carrytie carrier rollers. Y. f

ln operation the pulley 31 is revolved at suitable Yspeed and powertransmitted to each of the carrier rollers to positively drive them ateven surface speed and advance shells or other articles from place toplace. rEhe conveyer belt 11 which is employed for assisting in causingthe shells or other articles in transit to turn sharp corners consistsof pairsvof sprocket wheels 35 mounted upon each member of a pair of theshafts 2O in place of the carrier-.rollers 21.. The shafts which carrythe sprocket wheels 35 are Vdriven in the saine manner by sprockets suchas.\.are used on the shafts which carry thel carrier rollers and by thedrive belt 30, the only difference being that in the construction of theconveyer belt 11 a pair of link belts 36 and 37 traveling over thesprockets i 35 have secured to them closely spaced intervals transverseVbars or flights 38 (see Fig. 5), which are fastened by upturned ends 89and rivets 4:0 to ears or lugs/a1 formed on the sides of the links ofthe belts 86 and 87. Thus an endless belt is produced of flights intothe lap of which the shells or other articles are deflected during theforward movement of the upper side of the belt until the shells areturned at right angles and delivered longitudinally upon the drivenrollers 21 ofthe carrier and conveyed best embodiment thereof, but ldesire to have it understood that the Aconstructionshown is onlyillustrative andy that the invention can be carried out by other meansand applied to uses other than those above set forth within the scopeofthe following;
